    Prerequisites for Performing Factory Reset • Ensure that all the software images, configurations, and personal data are backed up before performing the Factory Reset operation.

    • Ensure that the device is not in the stacking mode as Factory Reset is supported only in the standalone mode. For Modular-chassis in high availability mode, Factory Reset is applied per supervisor.

    • Ensure that there is uninterrupted power supply when the process is in progress.

    • Ensure that you take a backup of the current image before you begin the Factory Reset process.

    • Ensure that neither In-Service Software Upgrade (ISSU) nor In-Service Software Downgrade (ISSD) is in progress before starting the Factory Reset process.

    Limitations for Performing Factory Reset • Software patches, if any, that are installed on the switch will not be restored after the Factory Reset operation.

    • If the Factory Reset command is issued through a vty session, the session is not restored after completion of the Factory Reset process.

    Information About Factory Reset Factory Reset removes all the customer specific data that has been added to the device since the time of its shipping. Data erased includes configurations, log files, boot variables, core files, and credentials like FIPS-related keys.

    Factory Reset 1

  • The following table provides details about the data that is erased and retained during the Factory Reset process:

    Table 1: Data Erased and Retained During Factory Reset

    Credentials like FIPS-related keys

    LicensesOnboard Failure Logging (OBFL) logs

    The Factory Reset process can be used in the following two scenarios:

    • Return Material Authorization (RMA) for a device—If you have to return a device to Cisco for RMA, remove all the customer-specific data before obtaining an RMA certificate for the device.

    • Recovering the compromised device— If the keymaterial or credentials stored on a device is compromised, reset the device to factory configuration, and then reconfigure the device.

    The device reloads to perform the Factory Reset task. Note that this reload results in a ROMMON mode.

    After the Factory Reset operation is complete, you can load the Cisco IOS image either through a USB or TFTP.
